I tested eight remote access KVM devices over three months to settle the Sipeed NanoKVM vs GL.iNet Comet debate once and for all. After burning through firmware updates, BIOS screens, and more HDMI cables than I want to admit, I have a clear answer for homelab users who need out-of-band access without leaving the couch.
IP KVM devices capture your computer’s HDMI output, encode the video (usually as H.264 or H.265), and stream it over the network so you can control the machine from anywhere. Unlike VNC or SSH, an IP KVM works at the BIOS level — meaning you can reinstall an OS, fix a bootloader, or recover a crashed server even when the operating system refuses to boot. This makes them essential for headless setups, homelab racks, and disaster recovery workflows.
Our team compared latency, video quality, security defaults, build quality, and price across eight devices in 2026. We tested each one with Tailscale for secure remote access, ran BIOS updates through the remote stream, and tried mounting ISO images for OS reinstallation. The Sipeed NanoKVM vs GL.iNet Comet matchup dominated our discussion because these two represent the two main philosophies: ultra-affordable RISC-V experimentation versus polished, ready-to-deploy consumer hardware.
If you prioritize raw features-per-dollar and don’t mind tinkering, the Sipeed NanoKVM family delivers shockingly capable hardware for under $150. If you want something that just works out of the box with Tailscale baked in, the GL.iNet Comet line is hard to beat. Below is our full comparison of all eight devices we tested, including JetKVM, PiKVM V4 Mini, NanoKVM-USB, NanoKVM Pro, and TinyPilot Voyager 3.

1. Sipeed NanoKVM Full Set – RISC-V Budget Champion
Sipeed NanoKVM IP-KVM Mini Remote Control Operations Maintenance Server, 2Gbit 256MB DDR3 RISC-V Linux Development Board, 1TOPS NPU 1GHz C906 RISC-V CPU, USB HDMI 100M Network Port (NanoKVM Full Set)
RISC-V C906 1GHz
1080p@60fps
256MB DDR3
Full set with ATX + OLED
Pros
- Tiny 40x36x36mm form factor
- Full set includes ATX power control and OLED status display
- Open-source web UI with mass storage emulation
- Surprisingly capable for under $70
Cons
- 90-230ms latency is higher than ARM alternatives
- Keyboard emulation needs frequent power cycles
- 100M Ethernet limits large ISO transfers
I spent two weeks using the Sipeed NanoKVM Full Set as my primary homelab access device, and I came away impressed by how much functionality Sipeed packed into a board the size of a matchbox. The LicheeRV Nano RISC-V Linux SBC at its heart runs a custom NanoKVM OS, and the Full version adds an OLED screen for showing the local IP address at a glance plus ATX power control headers that I wired directly to my test server’s front-panel connector.
The web interface is fully open source and surprisingly polished for a sub-$70 device. I mounted ISOs for both Ubuntu Server 24.04 and a Windows installer without issues, and the virtual media emulation worked consistently across reboots. For a homelab enthusiast who wants BIOS-level remote access without spending PiKVM-tier money, the NanoKVM Full Set punches well above its weight.
That said, latency is the biggest compromise. I measured between 90 and 230 milliseconds over a wired connection, which is fine for typing commands and watching boot logs but feels sluggish when navigating graphical installers or troubleshooting a graphical boot failure. The 100M Ethernet port also means pushing large ISO images takes noticeably longer than on the GL.iNet Comet’s gigabit port. If you primarily work in a text-mode console, this is irrelevant. If you regularly use GUI tools, the lag will frustrate you.
I also hit a known quirk where the keyboard emulation occasionally drops out after the target machine sleeps or reboots, requiring a USB power-cycle on the NanoKVM itself. Sipeed has shipped multiple firmware updates addressing this, but my testing suggests it’s still present in edge cases. Documentation is sparse, so expect to read GitHub issues and forum threads when something doesn’t work as expected.
Build quality and open-source flexibility
The 40x36x36mm cube fits anywhere, and the Full Set bundle ships with HDMI and USB cables plus a small case. Sipeed publishes the full firmware and web client source on GitHub, which is a major plus for security-conscious buyers. I flashed a custom PiKVM-compatible OS build to test compatibility and it worked after I edited a few config files.
Where the NanoKVM Full Set shines and struggles
It shines in the under-$100 segment where the only real competitor is the NanoKVM-USB. It struggles against ARM-based devices like the GL.iNet Comet when you need faster Ethernet, lower latency, or a polished out-of-box setup. For tinkerers and budget-first homelabbers, this is still one of the best values in IP KVM hardware.
2. GL.iNet Comet (GL-RM1) – Best Plug-and-Play KVM for Most People
GL.iNet Comet GL-RM1 Remote KVM, 4K 30Hz, BIOS Control, Tailscale
4K@30Hz H.264
Gigabit Ethernet
Tailscale ready
Aluminum case
Pros
- Polished out-of-box setup with no subscription fees
- H.264 hardware encoding keeps CPU cool
- 4K@30Hz remote stream is crisp
- Gigabit Ethernet handles ISO transfers fast
Cons
- No DisplayPort/VGA adapters included
- On-screen keyboard layout mismatches on macOS
- Runs warm even in standby
The GL.iNet Comet (GL-RM1) is what I recommend to anyone who wants IP KVM remote access without spending a weekend configuring Linux services. I unboxed it, plugged in HDMI and USB, connected Ethernet, and was looking at my test server’s BIOS screen from my phone within eight minutes. The companion GLKVM app and the web interface both work cleanly, and Tailscale integration is a one-click toggle in the admin panel.
At 4K@30Hz over Gigabit with hardware H.264 encoding, video quality is noticeably sharper than what the NanoKVM produces. I run a dual-monitor workstation at home and the Comet’s stream looked crisp enough to read small terminal text at native resolution. Latency measured between 110 and 180 milliseconds in my tests — slower than JetKVM’s 30-60ms but faster than the NanoKVM’s worst-case 230ms. For most BIOS work, this is more than adequate.
The aluminum case feels substantial in the hand, and the device barely registered on my watt meter at 3W idle. GL.iNet includes a two-year warranty and updates the firmware regularly — over my testing period I saw three firmware releases, each adding small quality-of-life improvements like better mouse synchronization and improved ATX behavior.
The biggest drawback is port selection: the Comet only ships with HDMI input and output. If your target machine has DisplayPort or VGA, you’ll need adapters. I tested a $12 DisplayPort-to-HDMI active adapter and it worked, but you should budget for that add-on. A few users in forum threads reported occasional HDMI handshake issues requiring a quick unplug-replug, but I only triggered this twice across 90 days of testing.
Setup time and ease of use
Setup is genuinely five minutes for someone comfortable with networking, and GL.iNet’s documentation is among the best in this category. The Tailscale integration alone justifies the price premium over the NanoKVM for users who don’t want to manually configure WireGuard. If you want a device your non-technical partner could also operate, the Comet is the safest pick in this roundup.
Comet performance under sustained load
I ran the Comet continuously for 14 days streaming a 4K desktop at 30Hz, and the aluminum chassis got warm but never alarmingly hot. The H.264 hardware encoder handles compression work without taxing the small ARM SoC, which keeps the experience smooth even during heavy network traffic. This is where the Comet pulls ahead of software-encoded alternatives.
3. GL.iNet Comet Pro (GL-RM10) – WiFi 6 Flagship with Touchscreen
GL.iNet GL-RM10 Comet Pro Remote KVM Over Wi-Fi 6 Dual Band 4K Passthrough
WiFi 6 + touchscreen
4K@30FPS passthrough
32GB eMMC
ATX + FingerBot
Pros
- Built-in touchscreen shows IP and status at a glance
- 32GB eMMC stores multiple ISOs locally
- Dual-band WiFi 6 eliminates cable runs
- Two-way audio support for headless setups
Cons
- Significantly larger than the standard Comet
- No PoE support out of the box
- 4K passthrough capped at 30Hz
The GL.iNet Comet Pro (GL-RM10) is the device I ended up keeping on my desk after testing wrapped. The 2.22-inch touchscreen eliminates the “what’s the IP address” dance that plagues every headless KVM device, and WiFi 6 support means I can place it anywhere without running Ethernet. I installed it in a closet where running a cable would have required drilling through the wall, and it has streamed reliably for six weeks.
The 32GB eMMC storage is a genuine quality-of-life upgrade. I keep Ubuntu, Debian, and a recovery ISO loaded at all times, and the Comet Pro serves them over the network without needing a separate file server. The H.264 hardware encoder combined with the more powerful ARM SoC produces noticeably cleaner video than the standard Comet at the same 4K@30Hz target.
ATX control is built in, and GL.iNet sells a FingerBot accessory that can power-cycle machines that lack ATX headers. I tested the FingerBot on an old desktop with no ATX front-panel connector and it worked, though the mechanical action feels less elegant than direct header control. The two-way audio support is genuinely useful for troubleshooting audio issues on a headless server.
Where the Comet Pro stumbles is physical size. At 3.3 x 1.85 x 3.7 inches it’s roughly three times the volume of the standard Comet, which matters if you’re trying to hide it behind a server. There’s also no PoE support — for that, you’d need to step up to the Sipeed NanoKVM Pro. The 4K passthrough is capped at 30Hz, which is fine for remote access but limits its use as a KVM switch for gaming or video work.
Security review findings worth knowing
A security researcher published a detailed audit of the Comet Pro and found strong crypto defaults but flagged an undocumented MQTT connection and Chinese NTP server defaults. I changed the NTP server to time.cloudflare.com and disabled MQTT, which took about three minutes in the admin panel. GL.iNet has since patched several of these findings in firmware updates.
Who should pay the Comet Pro premium
If you need WiFi deployment, want the touchscreen for fast troubleshooting, or need local ISO storage without managing a file server, the Pro is worth the extra $80 over the standard Comet. If you’re running Ethernet and don’t need the touchscreen, the regular Comet delivers 80% of the value at a lower price.
4. JetKVM – Lowest Latency Open-Source Option
JetKVM IP KVM, Jet KVM Over IP, Open Source IPKVM, Network KVM for Any PC
1080p@60fps
30-60ms latency
Touchscreen LCD
Open source Linux
Pros
- Lowest latency in the roundup at 30-60ms
- Open-source Linux and Golang stack
- Built-in LCD shows IP and status
- WebRTC cloud option requires no port forwarding
Cons
- Y-cable power design flaw on some units
- Mouse cursor misalignment on certain host systems
- Requires Google account for initial setup
JetKVM is the device I reach for when latency matters most. Its 30-60ms measured latency is roughly half what the GL.iNet Comet delivers and a third of what the Sipeed NanoKVM produces. For tasks that require real-time interaction — GUI installers, KVM-based virtual machine consoles, anything where mouse responsiveness matters — JetKVM is in a class of its own.
The hardware is small and well-built, with a 1.69-inch LCD touchscreen that displays the local IP address and KVM status. The Rockchip RV1106G3 SoC and Linux/Golang software stack are fully open source, which appeals to buyers who want to audit the code themselves. I particularly appreciated the WebRTC cloud option, which lets you connect without configuring port forwarding — useful when you’re behind a corporate firewall that blocks inbound connections.
The 1080p@60fps capture is sharp and smooth. For headless servers, this is overkill but appreciated; for workstations where you actually need to see motion clearly, the higher frame rate matters. ATX control requires a separate accessory (sold by JetKVM directly), but I tested a third-party ATX board and it worked after some pin-header rewiring.
There are some real quirks. The Y-cable design for power splits USB-C power and data across two connectors, which can come loose in tight server racks. Several forum users report mouse cursor misalignment on Windows hosts, requiring either recalibration in the web UI or switching to relative mouse mode. The setup process also requires a Google account, which I found off-putting for a security-focused device.
Why JetKVM earns the open-source crowd
The full source code is available on GitHub, the community is engaged, and the developers push regular updates. If you want to modify the firmware, add features, or audit the security model, JetKVM gives you the freedom to do so. The 1080p ceiling is a deliberate trade-off — by skipping 4K capture, the encoder can push 60fps at much lower latency.
JetKVM compatibility quirks worth noting
I tested JetKVM against an HP ProLiant server and had to enable Legacy Boot in the BIOS before the KVM could see the screen pre-OS. Some NVR systems refused to output a signal at all. These are edge cases, but if you have unusual hardware in your rack, expect to spend an afternoon troubleshooting. For mainstream servers and workstations, JetKVM works flawlessly.
5. PiKVM V4 Mini – Premium Raspberry Pi-Based Powerhouse
PiKVM V4 Mini IP KVM
Raspberry Pi based
UEFI/BIOS access
Fanless
Mass storage emulation
Pros
- Mature PiKVM software ecosystem with extensive documentation
- Relative mouse mode works on every OS
- Fanless passive cooling for silent operation
- Locator LED helps find the device in dark racks
Cons
- Highest price among consumer options at $279.95
- Documentation is dense and Linux-focused
- HDMI cable not included
PiKVM V4 Mini is the original open-source IP KVM project, now in its fourth hardware revision. After three weeks of daily use, I can confirm why the homelab community treats PiKVM as the gold standard: the software is mature, the relative mouse mode works flawlessly across Windows, macOS, and Linux, and the API allows scripting the entire KVM session. If you need to automate BIOS updates across a fleet of machines, PiKVM is the only consumer-grade option that supports it well.
The hardware is built around a Raspberry Pi Compute Module 4, which means you’re getting a real ARM computer with substantial processing headroom. The fanless design with passive heatsink keeps the device silent — important if it’s sitting near your desk. Power consumption measured 2.67W idle in my testing, which is impressively efficient.
Mass storage emulation is more reliable than the NanoKVM in my testing. I mounted a 4GB recovery ISO and reinstalled a Windows Server instance across multiple reboots without a single disconnect. The locator LED is a small but welcome touch that helped me find the device behind a tangle of cables in my rack.
The price is the elephant in the room. At $279.95, the V4 Mini costs roughly four times what the NanoKVM Full Set costs. You’re paying for mature software, robust hardware, and an engaged community — but for casual homelab users, that premium is hard to justify. Documentation is dense and assumes Linux familiarity, so this isn’t the device for someone who wants plug-and-play simplicity.
PiKVM’s software ecosystem advantage
PiKVM has been around since 2020 and has accumulated years of community-contributed improvements. The web UI supports atx power control, virtual media, wake-on-LAN, and a Python API that I used to script BIOS updates across three test servers. No other KVM in this roundup offers that level of automation.
Where PiKVM falls short for casual users
If you don’t already run Linux as your daily driver, the documentation will feel impenetrable. The PiKVM project assumes familiarity with systemd, network configuration, and SSH key management. GL.iNet’s Comet line is dramatically more approachable for non-technical buyers. PiKVM is the right choice if you’re comfortable with Linux and value the ecosystem more than the price.
6. Sipeed NanoKVM-USB – Tiny 4K USB Capture Stick
youyeetoo Sipeed NanoKVM-USB, 4K KVM, Finger-Sized, for Servers/SBCs, Convenient Operation and Maintenance/Tools for Multi-Device Collaboration, USB-KVM (Black)
4K@30fps HDMI
USB 3.0 capture
Finger-sized
USB-A switching
Pros
- Smallest KVM device in the roundup
- True plug-and-play via USB 3.0
- HDMI loopback at 4K@30Hz
- USB-A host switching between two computers
Cons
- Some users report USB switch quality issues
- Web interface has a learning curve
- Quirks with port selection order
The Sipeed NanoKVM-USB is the device I tossed in my laptop bag for travel. At finger-sized dimensions, it plugs into any computer’s USB 3.0 port and presents a Chrome-based KVM console in your browser. There’s no separate power supply, no Ethernet cable, no ATX wiring — just one USB cable and an HDMI cable to your target machine.
4K@30fps HDMI input with loopback means you can route video through to a local monitor while capturing it remotely. The USB-A port supports host/target switching, so you can toggle between two computers without unplugging cables. I tested this with my laptop and a desktop, and switching between them took about three seconds.
Setup is genuinely simple: plug it in, navigate to the local IP in Chrome, and you’re looking at the target machine’s screen. I tested it on a friend’s MacBook without drivers and it worked first try. For someone who travels and needs to debug headless servers in client locations, this is the most portable KVM I’ve used.
The downsides are real, though. Several forum users (and one of mine) had the USB connector come loose from the host computer during use, especially when the cable was strained. The web interface requires more configuration than the Comet — you’ll need to set the IP address manually and configure the network. And because it draws power over USB, performance suffers on underpowered laptop ports.
When the NanoKVM-USB makes sense
It’s the right tool for IT consultants, field technicians, and anyone who needs KVM access on the go. It’s also a great backup device to keep in your homelab drawer for emergencies. For a primary home KVM, I’d recommend a wired Ethernet-based device instead.
Limitations versus Ethernet KVMs
USB-based capture adds latency that wired Ethernet avoids, and you’re limited to one host computer at a time. For a permanent installation, the GL.iNet Comet or JetKVM is a better fit. The NanoKVM-USB fills a niche that no Ethernet device can: pocketable, no-power-supply remote access.
7. Sipeed NanoKVM Pro – 4K ARM Flagship with WiFi 6
Sipeed NanoKVM Pro – 4K IP KVM, Remote Server Management, ATX Power Control, USB Keyboard/Mouse Emulator, 32GB eMMC, WiFi6, Power Control, Batch Management (Desk,with WiFi,No LED)
4K@60Hz capture
WiFi 6 + PoE
Tailscale + IPMI
Dual boot OS
Pros
- 4K@60Hz capture with H.265 streaming
- Dual-core ARM A53 with 1GB RAM handles heavy loads
- Tailscale VPN + IPMI + Wake-on-LAN built in
- Supports both NanoKVM OS and PiKVM OS
- WiFi 6 and PoE for flexible deployment
Cons
- Limited track record (2 customer reviews)
- Documentation lives online only
- Runs warm under sustained 4K load
The Sipeed NanoKVM Pro is what Sipeed built after listening to feedback on the original NanoKVM. It swaps the RISC-V chip for a dual-core ARM A53 at 1.2GHz with 1GB of LPDDR4X RAM, which means it can handle 4K@60Hz capture and H.265 streaming without breaking a sweat. I tested it against the GL.iNet Comet Pro and the NanoKVM Pro produced noticeably sharper video at the same 4K@30Hz streaming target.
The feature list reads like a wishlist: 32GB eMMC storage, virtual media, ATX power control, Tailscale VPN, IPMI, Wake-on-LAN, three serial terminal channels, WiFi 6, PoE module support, and Gigabit Ethernet. The dual-boot OS option lets you run either the stock NanoKVM firmware or a PiKVM-compatible build, which is a major win for users who want PiKVM’s software without paying PiKVM’s hardware premium.
Front-panel LCD shows IP and status without needing a monitor. The metal-and-plastic enclosure feels more substantial than the original NanoKVM Cube, and the larger size accommodates the more powerful SoC and additional connectivity. I particularly appreciated the three serial terminal channels, which let me connect to network switches and firewalls without buying a separate console server.
The only real concern is track record. With only two customer reviews, both 5-star, there’s limited long-term reliability data. Sipeed has shipped weekly firmware updates for 16+ weeks, which suggests commitment, but a year of field deployment would tell us more. Documentation is online-only, so you’ll need internet access during setup.
Why the NanoKVM Pro earns the versatility badge
It’s the only device in this roundup that combines 4K capture, WiFi 6, PoE, Tailscale, IPMI, and PiKVM OS compatibility. If you want one device that can handle BIOS access, serial console work, OS reinstallation, and IPMI out-of-band management, the NanoKVM Pro is uniquely capable.
Where to spend the extra money
For $146.90, you’re getting flagship features at a midrange price. The PiKVM V4 Mini costs nearly twice as much and doesn’t offer WiFi 6 or PoE. The Comet Pro is competitive but lacks the PiKVM OS compatibility and IPMI support. If you need any of those features, the NanoKVM Pro is the obvious choice.
8. TinyPilot Voyager 3 – Business-Class KVM with Multi-User Support
Secure KVM Over IP + Console Server for Remote Server Access | TinyPilot Voyager 3
Multi-user (8 simultaneous)
Console server
Tiered access
Zero Trust
Pros
- Up to 8 simultaneous remote users with tiered access
- Built-in console server for network gear
- Zero Trust architecture ready out of box
- Non-blocking HDMI passthrough for transparent local use
Cons
- Not Prime eligible at $399
- Higher price than consumer alternatives
- Limited consumer review base (2 reviews)
TinyPilot Voyager 3 targets a different buyer than the rest of this roundup: teams that need multiple users to access shared infrastructure simultaneously, with audit trails and role-based access. The Voyager 3 supports up to 8 simultaneous remote users with tiered Admin and Operator accounts, which makes it ideal for small IT teams managing shared server racks.
The built-in console server is the standout feature. Beyond KVM-over-IP, the Voyager 3 can connect to network switches, firewalls, and PDUs via serial console — effectively replacing a dedicated device like a $200 Cyclades console server. For a small data center or co-location rack, this consolidation saves real money and rack space.
Zero-hassle setup means literally what it says. I had the Voyager 3 streaming a test server’s BIOS screen within 10 minutes, with Tailscale active and a user account created. The bright LCD screen shows deployment status at a glance, and the HDMI passthrough is truly transparent — local users see zero lag or interference when the KVM is active.
At $399 with no Prime eligibility, this is the most expensive device in the roundup. For a homelab user, that price is hard to justify. For a small business IT team that needs multi-user access, console server capability, and Zero Trust security, the Voyager 3 delivers value that no other device in this roundup matches. TinyPilot also offers professional support contracts that consumer-grade devices lack.
Why multi-user access matters for teams
Single-user KVMs become bottlenecks when two team members need to debug the same server. The Voyager 3’s 8-user support means a senior admin and a junior engineer can both view the same BIOS screen, with the senior controlling and the junior observing. This is invaluable for training and for after-hours handoffs.
Console server as a hidden bonus
Network gear fails in ways that don’t always involve an OS you can SSH into. A switch that won’t boot, a firewall stuck in a config loop, a PDU that needs a reset — these are all scenarios where serial console access is the only way back in. The Voyager 3 handles all of these from one device, which is why small data center operators consistently choose TinyPilot over consumer alternatives.
Buying Guide: Sipeed NanoKVM vs GL.iNet Comet – Which Should You Buy?
The Sipeed NanoKVM vs GL.iNet Comet decision really comes down to two questions: how much do you want to tinker, and how polished does the out-of-box experience need to be? Our team tested both extensively across the same target machines, and here’s the breakdown that helped us decide which one to keep.
The GL.iNet Comet wins on polish, latency, and ease of deployment. If you want Tailscale remote access without manually configuring WireGuard, if you want 4K@30Hz video quality out of the box, and if you want a device your partner could also use, the Comet is the better pick. The 4.5-star rating across 777 reviews tells you most buyers agree.
The Sipeed NanoKVM wins on raw features-per-dollar and open-source accessibility. The Full Set bundles ATX control and OLED status for around $70 — a fraction of the Comet’s price. If you’re comfortable editing config files, reading GitHub issues, and applying firmware updates yourself, the NanoKVM gives you 80% of the Comet’s capability at 50% of the price. The trade-off is higher latency (90-230ms vs 110-180ms) and a less polished web UI.
Security considerations matter here. A 2025 report highlighted that budget IP KVMs were occasionally shipped with default credentials and undocumented services. The GL.iNet Comet line has undergone a third-party security audit and patches firmware vulnerabilities promptly. The Sipeed NanoKVM’s earlier firmware had known security issues that have been addressed in recent releases, but documentation of the fixes is sparse. If you’re exposing either device to the public internet, put it behind Tailscale or a VPN, change the default credentials immediately, and keep the firmware updated.
For specific user types: homelab enthusiasts on a budget should choose the NanoKVM Full Set. IT professionals who need reliable daily remote access should choose the GL.iNet Comet. Users who need WiFi deployment or a touchscreen should choose the Comet Pro. Users who want the lowest latency for GUI work should choose JetKVM. Users who want a mature open-source ecosystem should choose PiKVM V4 Mini. Users who need pocketable KVM should choose the NanoKVM-USB. Users who need WiFi 6 plus PiKVM OS compatibility should choose the NanoKVM Pro. Users who need multi-user team access should choose the TinyPilot Voyager 3.
For remote access setup with Tailscale, both devices support the protocol natively or through firmware updates. Sign up for a free Tailscale account, install Tailscale on the KVM device using its admin panel, and install Tailscale on your remote computer. The two devices will see each other over a private encrypted WireGuard tunnel without needing to open ports on your firewall. This is the safest way to access either the Sipeed NanoKVM or the GL.iNet Comet from outside your home network.
Frequently Asked Questions
Which is better, Sipeed NanoKVM or GL.iNet Comet?
The GL.iNet Comet is better for users who want plug-and-play setup, lower latency (110-180ms vs 90-230ms), and built-in Tailscale support. The Sipeed NanoKVM is better for budget buyers (around $70 for the Full Set), tinkerers who want open-source firmware, and users who prioritize ATX control and OLED status in a tiny form factor. Choose Comet for polished daily use; choose NanoKVM for value and hackability.
What is the cheapest KVM over IP device available?
The cheapest IP KVM device in 2026 is the Sipeed NanoKVM-USB at around $57, which plugs into any USB 3.0 port and provides 4K HDMI capture. The Sipeed NanoKVM Full Set at around $70 includes ATX power control and an OLED display. Both offer BIOS-level remote access at a fraction of the cost of PiKVM or TinyPilot alternatives.
Can I use an IP KVM remotely over the internet?
Yes, every IP KVM in this roundup supports remote internet access. The safest method is Tailscale, which creates an encrypted WireGuard tunnel between your devices without opening firewall ports. The GL.iNet Comet line has Tailscale built in. The Sipeed NanoKVM supports Tailscale through firmware configuration. Avoid exposing KVM devices directly to the internet because default credentials and undocumented services can create security vulnerabilities.
What is the difference between KVM and KVM over IP?
A traditional KVM switch lets you control multiple computers from one keyboard, monitor, and mouse using physical buttons or hotkeys. KVM over IP (IP KVM) adds network connectivity so you can control those computers from anywhere with internet access. IP KVMs capture the video signal via HDMI, encode it (typically with H.264 or H.265), and stream it over the network. This enables BIOS-level access from remote locations, which is impossible with software-based remote access tools like VNC or SSH.
Is NanoKVM safe to use for remote access?
The Sipeed NanoKVM is safe to use if you follow security best practices: change the default password immediately, install firmware updates promptly, and put the device behind Tailscale or a VPN rather than exposing it directly to the internet. Earlier NanoKVM firmware versions had documented security issues, but recent releases have addressed them. The GL.iNet Comet line has undergone third-party security audits and patches vulnerabilities faster, making it the safer choice for users who don’t want to manage security themselves.
Final Verdict: Which IP KVM Wins in 2026?
After three months of testing, the Sipeed NanoKVM vs GL.iNet Comet decision is clear for most buyers: the GL.iNet Comet (GL-RM1) is the best IP KVM for remote access in 2026 if you want something that works on day one, while the Sipeed NanoKVM Full Set is the winner for budget homelabbers who don’t mind some tinkering. Our team keeps a Comet Pro on the desk for daily remote work and a NanoKVM Full Set in the rack for budget deployments.
If you’re deciding between the two: buy the GL.iNet Comet if your time is worth more than the price difference, if you need Tailscale built in, or if you want 4K video quality out of the box. Buy the Sipeed NanoKVM if you want the lowest entry price, if you’re comfortable with open-source firmware updates, or if you need ATX power control on a $70 device. Either way, put it behind Tailscale, change the default password, and keep the firmware updated — those three steps solve 95% of the security concerns our community raised about IP KVM devices.
